OORDINATION OF
+CLCC
AND
+CPAS
RESPONSES
In order to determine the call state of the A3LA-RM, the +CLCC and +CPAS commands may be
used. The following table demonstrates how the output of the two commands, as well as the
Extended Ring Message, can be combined to provide a more detailed definition of the call state
than any one of the results provides by itself.
